SOURCE: power loss, black smoke

Hi, the problem you are having is going to be with the turbo you will probably find one of the hoses going to the turbo has either come off or has a split in it.
It can be hard to find the split but this is the most likely cause of the problem.
As the car is losing power at high revs then this indicates that either the turbo itself has failed or it could just mean that their is a split in one of the hoses.

A split hose is the most likely cause you will need to inspect every part of all the hoses connected to the turbo. When these pipes get a split they dont then have the correct pressure for the turbo to work at best running conditions this is the smoke your seeing out the back.

a good way to check this is by the amount of oil in the car if your regular topping it up then this would mean looking deeper into the engine to find out why oil is getting into the cylinders but if you are not topping the oil up then this would mean their is no fault with the engine.

So have a good look around the turbo pipes give them a good squeeze the split might only tiny but that is all it takes to cause the problem your having.

If you are unsure at what to look for then its best left to a garage as they would have a good idea where the fault would most likely be.

Let me know if you need further assistance ok.

I have a 96 s10 sonoma 5speed i went to shift to third gear and its stuck. even in neutral it still in third gear. What do i need done ?

Did you try to pop the clutch? Did you mistakenly down-shift while still at high speed? did you try to down-shift for more torque while going uphill? You may have ruined your clutch.

But one of the guy's issue with the new 4bbl carb was that his floor mat under the accelerator pedal limited just how far open the second set of bbls could open so he had loss of power at higher speeds.

Loss of power

If you can feel power loss, from the first gear specially driving uphill. Yes it is your clutch.

Loss of power uphills and shifting improperly.

It sounds very much like your clutch is slipping. If the engine revs continue to rise when in gear and the car does not increase it's speed accordingly then if it is a manual car then you need a new clutch.

Loss of power and acceleration on Mazda 6 Turbo diesel 2003

I'm assuming that that smoke was more previlant while going uphill because that's when the turbo would be really spolling up to max psi. I would guess that if you really got on the gas hard and got the turbo going even on a flat surface, that you would notice the smoke too. The loss of power and the white/grey smoke are tell tale signs that your turbo is bad or starting to fail. Good luck!
